1. Are there any hotkeys for Construct? I'd like to specifically find hotkeys to copy/paste events, conditions and actions. Also a key to move back and forth from the layout to the event editor would be nice.
There are, but they generally aren't documented. A wiki page on this would be good, and more shortcuts for navigation also should be added in future.
[quote:onvu1ac7]2. I had this bug where I made a small physics object fall onto a larger immovable one. The small object just floated in the air above the larger one. It doesn't seem to detect a collision (I tried some collision detection events), but it just bounces off the air as if it hit something.
Did you enable gravity on the object you wanted to fall down?
Doppel's file is a good example for Q3 as well.
